With Captain Marvel fresh off its box office-conquering opening weekend, Marvel is already thinking ahead to its next blockbuster, having just dropped the official trailer for the superhero-infused crossover event of the year. The new Avengers: Endgame clip is clearly built to stoke fan anticipation. Every moment seems to have something important to say, and comes with the potential of deeper meanings, hidden explanations, and misleading misdirections. Let's break it down and take a look at the details you might've missed in the newest Avengers: Endgame trailer. And just so we're all clear — potential and rumored spoilers ahead...don't say we didn't warn you, y'all.

We've seen this before: the Avengers: Endgame Super Bowl spot opened on a quick sequence that sped through ten MCU characters, most of whom had died or been snapped in Infinity War. Everything was in black, white, and red all over. This time around, the red-highlighted footage is back, and also specifically highlights some different faces...like Tony Stark, Steve Rogers, Thor, and Okoye... four characters who did not get snapped. It's pretty widely known that Avengers: Endgame is the final movie in Chris Hemsworth, Robert Downey Jr., and Chris Evans' Marvel Studios contracts. That doesn't mean they're definitively done with their characters...but if you're gonna retire a role, you could do worse than saving half the universe, you know?

Meanwhile, that red coloring still seems highly symbolic. Red is often connected to blood and death. But — as we've theorized before — it could have something to do with the red Reality Stone and its possible usage in un-snapping the world. Will that gem be instrumental in defeating Thanos once and for all? If this montage means what we think it might, keep your eyes peeled for that scarlet stone...

One of the most exciting moments in the first trailer was the arrival of Scott Lang at the Avengers HQ with his Quantum-powered Ant-Van. While the presence of Lang in Endgame is a pleasant if not a particularly surprising revelation, one attention-getting moment occurred when Cap and Black Widow ask each other about what they're seeing:

Many detail-oriented fans seized on her not-quite-answer to suggest that the footage wasn't actually live. The word "Archive" in the upper left corner of the screen also led some to theorize that perhaps the security camera clip was, in fact, a very "old message"...and from a different year entirely.

In the new trailer, things seem to point toward a post-snap arrival for Lang. Ant-Man features heavily throughout the trailer, but one scene in particular shows a befuddled Scott looking at a telephone pole plastered with missing person posters. While this could be highlighting a particularly active day for kidnappers, chances are the scene puts Lang firmly after the snap as he starts to piece together what happened.

One of the biggest questions that's swirled since the dust from Infinity War settled was if, how, and when time travel would factor into Avengers: Endgame. Ant-Man and the Wasp explored the potential of the Quantum Realm, opening up the opportunity for that mode of inter-dimensional transportation to come into play in Endgame. And we know from that film's post-credits scene that the Quantum Realm is entangled with time travel in some way:

And as this newest trailer seems to indicate, it appears more and more likely that audiences will be pulled around the MCU timeline in Endgame. Keep watching the video to find Things only true fans noticed in the new Endgame trailer!

With allusions to previous MCU movies and references to comics that haven't made their way to the big screen, Avengers: Endgame reminds Marvel fans that the people behind the camera are just as enthusiastic as the ones filling the seats. Here are some lines in Avengers: Endgame that were more important than you may have realized.

If you saw Avengers: Endgame in a packed theater, then the moment Thor's hammer Mjolnir flies into Captain America's hand probably inspired one of the loudest and most enthusiastic responses from the audience.

If not, then it's at least met with enthusiasm from Thor himself, who yells "I knew it!" as he spots Cap threatening Thanos with the legendary weapon.

So what did Thor mean by "I knew it?" In an early scene in 2015's Avengers: Age of Ultron, Thor gives the rest of the team permission to try to lift Mjolnir. Thor sits back, confident none of his mere mortal teammates will prove worthy to wield the hammer… until Steve Rogers gives it a shot.

That brief nudge, and past comic book stories in which Cap has proven worthy of Mjolnir, left some fans theorizing that Cap could've lifted the hammer but chose not to in order to spare his teammate any humiliation.

Apparently, the Odinson was one of those fans. When Thor yells "I knew it!" he betrays that he thought Cap was faking way back in 2015 as well. And how couldn't he? Cap's as worthy as they come.

There's never quite been a movie like Avengers: Endgame. That's probably because there's never been a movie franchise like the Marvel Cinematic Universe. With over 20 interconnected movies released over the span of a decade, Endgame had ample opportunities to make tons of references and callbacks to a sprawling continuity of characters and plot twists. And while many significant lines of dialogue were pretty easy to spot like ...there were still plenty of other fantastic callbacks that may have flown over your head. Here are some of the small details you might've missed in Avengers: Endgame.

Beware: gigantic, world-ending spoilers ahead.

Throughout the film, we got lots of direct references to previous movies, but some are less obvious than others. For example, when Natasha Romanoff and Clint Barton fly their spaceship to Vormir to retrieve the Soul Stone, one of them quipped to the other, "we're a long way from Budapest." That refers back to a mysterious mission the two of them went on in their shared past that they referred to during the events of the first Avengers film.

Meanwhile, just before the un-dusted heroes all join Cap to fight Thanos and his army toward the end of the film, we hear Falcon jump on the radio to tell his partner: "On your left." That's a callback to when Cap kept lapping the Falcon when the two first met as competing joggers at the beginning of Captain America: The Winter Soldier:

But the most endearing and heartbreaking callback? When Happy Hogan chats with Morgan after her dad's funeral and he asks if she's hungry. She says she wants "cheeseburgers, " and Happy smiles, saying, "Your dad liked cheeseburgers, too."

That's a reference back to a scene early on in the very first MCU movie: when Happy and Pepper pick up Tony after his rescue from the Ten Rings and he demands two things: that Pepper call a press conference…and cheeseburgers:

Unless you spend a lot of time watching YouTube videos about the Marvel Cinematic Universe, there's a better than decent chance that you have no idea what Avengers: Endgame directors Joe and Anthony Russo look like. Well, you actually got a great look at one half of the directing duo you just may not have realized it at the time.

When the movie jumps five years forward in time, we catch up with Steve Rogers in his support group in Queens, New York. In that circle of trust is a man who says he and a date spent the whole evening talking and crying. That guy is Joe Russo, the younger half of the directors who also helmed three other epic MCU entries: Captain America: The Winter Soldier, Captain America: Civil War, and Avengers: Infinity War.

This also wasn't Joe Russo's first time in front of the camera, either. He appeared in an episode of Arrested Development, a show for which he and Anthony directed several episodes, as well as in their film You, Me and Dupree, and all three of their other MCU films though Joe's part as Bert the paparazzi in Infinity War hit the cutting room floor before the movie made it to theaters.

Whenever a new superhero is announced to appear in any given comic book movie franchise, a host of A-list names are always immediately linked to the role — and it was no different in the case of Captain Marvel AKA Marvel's Carol Danvers.

Of course, the role ultimately went to Oscar winner Brie Larson — and her eagerly-anticipated MCU movie will arrive on the big screen in 2019 — but it could have gone to any number of actresses, according to the rumour mill.

These five, however, seemed to come genuinely close to winning the role (and indeed could have, if the circumstances had been slightly different) — if the rumour mill is to be believed, that is.

The actresses in question are as follows; Jessica Chastain (The Help, Zero Dark Thirty, Interstellar, The Martian), Bryce Dallas Howard (Lady in the Water, Spider-Man 3, The Twilight Saga: Eclipse, Jurassic World), Yvonne Strahovski (Chuck, Dexter, 24: Live Another Day, The Handmaid's Tale), Charlize Theron (The Cider House Rules, Monster, Hancock, Mad Max: Fury Road), and Emily Blunt (Edge of Tomorrow, Sicario, The Girl on the Train, A Quiet Place). Which one do you think would have been best-suited for the role of Captain Marvel? Would you have preferred any of them to Brie Larson?

Captain Marvel is the introduction of the the most powerful hero in the MCU to date. It involves a complex web of characters new and old, and it's also a semi-prequel set in the '90s, which means there are a lot of questions left largely unexplored. Be warned, MAJOR SPOILERS AHEAD.

Captain Marvel gives us yet another wrinkle in the history of the Tesseract, the first Infinity Stone to make its way to Earth. We knew that the Tesseract, a.k.a. the Space Stone, was found by HYDRA in the 1940s, recovered by SHIELD after Captain America's disappearance, and then stolen by Loki in the 2010s.

Now, we know that Dr. Wendy Lawson, a.k.a. Mar-Vell, was a gifted Kree scientist who used the Tesseract as part of her work on Project Pegasus, using it to power a lightspeed engine before her death sometime around the late '80s.

In the six years between Mar-Vell's death and the rise of Carol Danvers as a superhero, the Tesseract apparently just sat hidden in her cloaked, orbiting lab, which raises a few questions. She was presumably allowed the use of it by S.H.I.E.L.D., so why didn't SHIELD come looking for it when she died? How could something so important go missing for so long?

One of the standout stars of Captain Marvel is Goose, Mar-Vell's quote unquote cat. By the end of the film, it's revealed that Goose is a Flerken, an alien species that looks like an Earth feline on the outside, but also packs deadly tentacles and the ability to consume objects several times its size.

During the film's climactic moments, Goose devours several Kree warriors, intimidates other aliens, and even eats the Tesseract so Fury won't have to touch it. Because we know what happens when the wrong people touch Infinity Stones.

Then, in the post-credits scene, we see Goose hwark the Infinity Stone up onto Fury's desk and back into S.H.I.E.L.D. custody. Is Goose still hanging around the MCU somewhere? We may never know, but Goose and Fury seem like good pals. Keep watching the video to hear more of the biggest unanswered questions in Captain Marvel.

The latest trailer for 'Avengers: Endgame' was just as cryptic as the previous ones, but it did offer some intriguing new footage and a few hints as to where the story might go. What do the glimpses of the past mean? Who is Hawkeye training? Exactly how much time has passed since The Snap? And what's with Black Widow's hair? Check out the video to discover what we learned, and let us know what we missed in the comments!

As we buckle in for the forthcoming premiere of Avengers: Endgame, there are a lot of moving parts to keep track of: after all, we're talking about 21 movies over about a decade. It's the perfect time to look back over the history of the Marvel Cinematic Universe and go over everything fans should have in mind before scanning that ticket, ordering some popcorn, and settling in for Marvel's cinematic event of the year. A quick word of warning: spoilers for Captain Marvel ahead!

One consistent thread throughout many of the MCU's films before Infinity War has been the impending approach of Thanos. We saw elements of the Mad Titan all the way back in the first Avengers movie, when we caught a shot of his grinning face in the mid-credits scene. He played a role in the Guardians of the Galaxy franchise as well and reappeared at the end of Avengers: Age of Ultron when he donned an Infinity Gauntlet.

Infinity War brought Thanos crashing into the primary narrative, as the big purple one traipsed around the galaxy, gathering up the Infinity Stones. He already had the Power Stone when the film began, and his encounter with Thor and the surviving Asgardians in Infinity War's opening moments left him with the Tesseract, which hid the Space Stone. He proceeded from there to get the Reality Stone on Knowhere, the Soul Stone on Vormir after sacrificing Gamora, and the Time Stone after Doctor Strange surrendered it to him on Titan. Last but not least, he headed to Wakanda, where he plucked the Mind Stone out of Vision's forehead, completed his gauntlet, and snapped his fingers, wiping out half of the life in the universe in what has been dubbed "the Decimation."

Over time, the Avengers lineup has come to include characters like War Machine, Scarlet Witch, Vision, Falcon, and Spider-Man, but it all started with the Big Six. As The Avengers played out, a nucleus of heroes slowly came together, including Hulk, Iron Man, Hawkeye, Thor, Black Widow, and Captain America. 2016's Civil War saw the group split, with Cap, Hawkeye, and Black Widow heading off into exile in the aftermath.

While almost everyone was involved in Infinity War, the heroes weren't fully unified throughout the film. But as savvy fans quickly realized, as the dust from the Decimation settled, not one of the original Avengers had been dusted. Half of the universe's population may be gone, but it sure is convenient that all six of the original Avengers survived the dusting… isn't it? Make sure you continue to watch this before you see Avengers: Endgame!
